wifi disconnects after minutes

Buster

Code: Select all

lspci: Network controller: Intel Corporation Wireless 3165

Code: Select all

ip addr: wlp1s0

I think wlp1s0 is the proper driver, and I tried updating it, but the problem persists..
Wifi connects and works just fine, but after a few minutes cannot connect to any website yet it says it is still connected to the wifi..

wlp1s0 refers to your wireless LAN. It used to be wlan0 but is now more changeable.

In Linux the drivers are built into in the Kernel. What you add is the firmware. The firmware for your wifi is firmware-iwlwifi

How much RAM have you got?

What wifi interface are you using? https://wiki.debian.org/WiFi/HowToUse

Thanks for the correction. As from the guide you sent me...
I did

Code: Select all

ip link show

got the same wlp1s0, im sure this is the interface.
As for RAM, it says im using around 700mb out of 8gb.
After testing a failed ping command, I also ran a wireshark capture on previous mentioned interface and observed mainly ARP broadcasts from my device to the router 192.168.1.127.
This same situation happens on multiple different wifis, while my phone will have no problems...

I want to note again, this happens after a few minutes of good connection, then suddenly it stops, all pings fail, but kde plasma wifi gui still interface is connected to the wifi (and wireshark shows ARP broadcasts).

There is a thread in the HowTo section devoted to tweaking the iwlwifi driver to overcome problems like this, I suggest that you find it and read it.
